To do slow mo on TikTok, you can either slow your video while recording or add a slow-motion effect after you’ve recorded/uploaded a clip.

Built‑in slow mo while recording

Use this if you want the whole clip recorded in slow motion.

  • Open TikTok and tap the + button to create a new video.
  • On the recording screen, tap Speed (usually near the top or side of the screen).
  • Select a slower speed like 0.5x or 0.3x.
  • Hold the red Record button and film your clip; it will automatically record in slow motion.
  • Tap the checkmark, add sounds, text, or filters, then post as usual.

Add slow mo after recording

Use this if you want only part of the video in slow motion (for example, a hair flip or jump).

  • Open TikTok, tap + , then either record a video or tap Upload to pick one from your gallery.
  • Tap Effects on the editing screen.
  • At the bottom, choose Time and then tap Slow Motion (Slow‑mo).
  • A green bar/handle appears on the timeline; drag it to select which part of the clip should be in slow motion.
  • Preview your video; if it looks good, tap Save (or Next), then add your caption and post.

Tips for better slow‑mo TikToks

Slow‑mo tends to look best when it highlights movement or emotion.

  • Film with good lighting so the slowed video stays sharp and clear.
  • Use slow mo on hair flips, jumps, outfit transitions, or reaction shots to make them more dramatic.
  • Add music that matches the beat drop where your slow motion starts for extra impact.

Many creators in 2025 mix normal speed with a short slow‑mo moment (like a transition or reveal) to match current TikTok editing trends.

TL;DR: Use Speed 0.3x/0.5x before recording for full‑clip slow mo, or use Effects → Time → Slow Motion after recording to slow just part of the video.
